I store a split in the fridge. Last time I made some was at thanksgiving, as a proper turkey sandwich requires sourdough.
I needed to feed this on the counter for 4 days to get it up to speed. The first loaf usually needs a pinch of yeast to help. After getting the starter out of the fridge, I end up making 4 loaves (about 1 per day). We eat 1 and 4, while giving 2 neighbors 2 and 3.
